 -Change the logger class to use cout instead of printf. Consider how easy variable argument support would be.
 -Change all error messages to use the logger class so they get printed to the log file as well.
--Make sure fullscreen works correctly on OSX. Check the book to see how to handle Retina Display.
 -Add code to allow for resizing/maximizing the window
+-Add logic to make imgui element placement depedent on the window size so it works in fullscreen
 -Check the book's "Printing Parameters from the GL Context" to output a bunch of OpenGL context params
 -Move some common functions into a Utils class

 -Print a warning if texture images don't have sizes of 2^x
 -Fix the texture-mapping code to not flip the texture upside down.

 1. Remove buffer re-assignment when creating shader model groups
-2. Inside populateBuffers, check for the object type and resize all buffers of that type (will eventually do this in a loop)
 3. In copyObjectData, set vertex_vbo_offset for the object type only using numPoints, not vbo_base
 4. in renderScene, change the glDrawArrays call to use an offset of 0

       No, you're misunderstanding how this works. UBO binding works exactly like texture object binding.
